Specification of Letters Patent.

Patented May 21, 1907.

Application filed July 14,1905. Serial No- 269,665.

To. all whom it may concern.-

Be it known that I, ALFRED SPIoE, a citizen of the United States ofAmerica, and a resident of'New York city, in thecounty of New York andState of New York, have invented certain new and useful Improvements inSwings, of which the following is a specification.

This invention relates in general to amusement devices, and particularlyto that class of amusement devices in which passengers are subjected tocomplex or unusual motions, and. comes more specifically under the designation of swings.

The object is to produce a simple and comparatively'inexpensivecontrivance by which passengers are carried through novel and surprisingmovements.

The principle made use of is that illustrated by the Blackburn doublependulum, also by the oscillograph, both well known to physicists; and,in addition to the rise and f all due to the arc of the swing, the pathover which the passengers are carried is that of a Lassajouss figure,sometimes called acoustic figures, and also well known.

Defined in a general way, the invention consists of a supporting frame,a car for carrying passengers, and a Blackburns double pendulum by whichthe car is suspended to freely swing from the frame.

More specifically, the invention consists of a tower-like frame of asuitable height, a car for the passengers, a Blackburns double pendulumby which the car is suspended from the top of the frame, means foradjustin the Blackburns pendulum to vary the re l ative relation to eachother of its two different isochronous periods, a device for pulling thecar aside from its position of equilibrium and then releasing it,allowing it to swing freely, and a braking arrangement for bringing thecar to a stationary condition at will. The car, of course, is

pulled aside in a direction diagonal to a line joining the points ofsuspension of the pendulum from the frame, in order to obtain by gravitythe resultant motion necessary to cause the car to describe theLassajouss figure. Of course in the present device the pendulum andconsequently the figures described by the car, are of giant size. Theheight of the supporting frame is determined according to the amplitudeand the absolute periods in. which it is desired that the car shallswing.

For further and more minute details of construction reference will behad to the accompanying drawings.

Figure 1 is a side elevation of the complete device. Fig. 2 is an endelevation of what is shown in Fig. 1, as viewed from the right ofFig. 1. The dotted lines in Figs. 1 and 2 show the radii and the arcs ofthe swing of the car. Fig. 3 is an enlarged view in elevation of thepulley wheel and its adjuncts as seen in Fig. 1, portions of the cablesbeing broken away. Fig. 4 is an elevation of what is shown in Fig. 3 atright angles thereto and from the right, the parts being in the sameposition as seen in Fig. 2. Fig. 5 is an enlarged and detached view inelevation of the car and its appurtenances as seen in Fig. 1, portionsbeing broken away. Fig. 6 is an enlarged detached elevation of the earand its appurtenances, as viewed from the right of Fig. 5, with portionsbroken away. Fig. 7 is a plan of what is seen in Figs. 5 and 6, with theaddition of a plan view of the post and catch seen in elevation in Figs.1 and 2. Fig. 8 is a perspective dia gram of the three adjusting cablesand the two drums upon which they wind, all else being omitted, so as toclearly show the number and positions of the cables. The cables are asthey would appear when viewed diagonally from the front and left ofFig. 1. Fig. 9 shows one of the Lassajouss figures which the car may bemade to describe, the oscillations required to produce this figure beingin the ratio of 2.to 3. Fig. 10 is a side elevation of a modification ofthe device, the starting motor and its adjuncts being omitted. from thedrawing. In this modified form of the invention no adjusting means isprovided for the pendulum. Fig. 1 1 is an end elevation of what is shownin Fig. 10. Fig. 12 is an en larged view of the connecting block for thependulum, the View being the same as in Fig. 11, but the constructionbeing slightly modified over that shown in Fig. 1 1 by having the twoeyes for the lower cables placed between the two clevises for the uppercables, instead of outside thereof, on the common pin. Fig. 13 is a viewfrom the left of Fig. 12, with the addition of a modified constructionover that shown in Figs. 1.0 and 11 for attaching the ends of the uppercables to the supporting frame, the said cables being broken away.

Referring to Figs. 1 to 9 inclusive, 1 is a supporting frame, of anysuitable material, such as wood or steel, and from which issuspended'the car 2 by the cables 3, 4 and 5.

The height of the frame 1. may be anything desired, according to thetime it is desired shall be consumed by the car 2 in making a swing, forexample, a height of fifty feet would. give a period of about fourseconds to the major oscillation. The base of the frame is suflicientlywide to allow ample clearance for the swinging car in all directions.Means is provided for adjusting the said cables so as to vary the pathdescribed by the car 2, also mechanism for starting and stopping theswinging of the said car, all of which will now be described in detail.6 is a pulley block carrying the pulley'wheel 7 mounted loosely upon theshaft 8 which forms a pin for the two clevises'9 and 10 to which areattached respectively ends of the cables 3 and 4 which diverge from eachother in an upward direction and pass respectively over the pulleys 11,

and 12 and then over the pulleys 13 and 14, all of the said four pulleysbeing carried by the frame 1 and arranged in horizontal alinement witheach other, the pulleys 13 and 14 being directly above the pulley block6 and the pulleys 11 and 12 at opposite sides of the top of the frame 1,as shown. After leaving the pulleys 13 and 14 respectively the cables 3and 4 pass downward through the guiding apertures 15 and 16 respectivelyin the shaft 8 to the car 2, where both are attached to and wind uponthe same side of a double coned drum 17 fixed upon a shaft 18 supportedin a framework 19 carried by the said car. Why the drum 17 is coned willpresently appear. A third cable 5 is attached to the car 2 at 20, passesupward over the pulley wheel 7, and then back to the car 2, where it issecured to and winds upon a cylindrical drum 21 in the same directionthat the cables 3 and 4 wind upon the drum 17, the drum 21 being fixedupona shaft 22 which is mounted in the framework 19. On the shafts 18and 22 respectively are fixed two intermeshing' gears 23 and 24; fromwhich it is obvious that the two drums 17 and 21 must always rotatetogether but in opposite directions; and it also follows, from thedetails of construction already given, that if the said drums be rotatedthe cables 3 and 4 will be wound up on the coned drum 17 while the cable5 will be unwound from the cylindrical drum 21, or vice versa, accordingto the directions of rotation of the drums. The drums may be rotated bythe motor 25, having a pinion 26 which meshes with the gear 23, and maybe locked in a stationary position by inserting the removable pin 27through the gear 23 into the framework 19. When the cables 3 and 4 arecaused to be wound upon the coned drum 1.7 it is clear that the pulleyblock 6 will be raised and the distance shortened between a line joiningthe pulleys 11, 12, 13 and 14, and the aXis of the shaft 8, and at thesame time, if no way of compensation were provided, the car 2 would beraised equally with the block 6; but while the cables 3 and 4 arewinding upon the drum 17 the cable 5 is unwinding from the drum 21, andit is apparent that the effect of the unwinding of the cable 5 will beto increase the distance between the block 6 and the car 2 the finalresult being that the car 2 remains practically at the same height whilethe pulley block 6 moves up or down as the drums 17 and 21 are rotatedin the one direction or the other, the various coacting parts beingrelatively so proportioned as to produce this effect. As the cable 5does not attach directly to the block 6, but passes over the pulleywheel 7, it is evident that in order to move the block 6 the samedistance, twice the length of the cable 5 must be wound or unwound as ofthe cables 3 and 4, and this is brought about, as shown, by making thegear 24 with half the number of teeth, and of half the size, of gear 23,the two drums 17 and 21 being of substantially the same size; but it isobvious that the same result could equally well be accomplished bymaking the two drums of different sizes and the gear wheels of the samesize. Owing to the convergence of the cables 3 and 4 from the pulleys 11and 12 respectively to the block 6, it is apparent that the resultantmotion of the block 6 will be slightly greater than the distancetraveled by the cables 3 and 4 in winding on the drum 17, also that thisdiscrepancy increases as the cables 3 and 4 are wound up. To compensatefor the increasing angle of the cables 3 and 4 to each other from theblock 6, the drum 17 is doubly coned and the cables 3 and 4 wound fromthe larger toward the smaller portions, so that in winding constantlyless and less of the cables 3 and 4 is taken up. This compensation,while not precisely exact, is sufficient for all practical purposes.Mounted upon the car 2 is a second motor 28 which carries a third drum29 upon which winds a fourth cable 30 having at its free end a loop 31,and a hand brake 32 is provided for the drum 29. 'Lo cated in astationary position just outside of the limit of swing of the car 2, andat about a midway position within one of the angles which would beformed by planes extended downwardly from a line joining the pulleys 11,12, 13 and 14, and from the aXis of the shaft 8, as shown in Figs. 1, 2and 7, is a post 33 carrying a bracket 34 in which is pivoted a catch 35by the pivot pin 36, the catch 35 being for receiving the loop 31 of thecable 30. Fastened at the edge of the car 2 adjacent to the motor 28 isa trip plate 37, for contacting with the lower end of the catch 35 andthus causing its upper end to be withdrawn below the upper surface ofthe bracket 34 and at the same time from the loop 31 of the cable 30 forreleasing the same when the said cable is sufliciently wound upon thedrum 29 by the motor 28, which is ITO called the starting motor becauseit is used for drawing the car to one side from its position ofequilibrium, after which the car is automatically released, by the plate37 coming in contact with the lower end of the catch 35, and is leftfree to swing. The car 2 may be stopped from swinging at will bythrowing the loop 31 of the cable 30, which is already mostly wound uponthe drum 29, over the catch 35, at one of the positions of momentaryrest of the car and when it is near by, and applying the brake 32 to thedrum 29 just suiflicientlyto let the car 2 gradually lower to itsposition of equilibrium. The car 2 is free to swing in one directionfrom the pulleys-11, 12, 13 and 14 as a fulcrum, and also in a directionat right angles thereto from the shaft 8 as a fulcrum.

In the modified form ofthe invention shown in Figs. 10 to 13 inclusive,38 is a supporting frame, similar to the frame 1, from which issuspended the car 39 by the two cables 40 and the four cables 41, one ofthe cables 41 being concealed behind the others. 42 is an intermediateblock consisting of the two clevises 43, the two eyes 44, and the shaft45 which forms a pin for the said clevises and also passes through thesaid eyes and is held in place by cotter pins 46. The two cables 40attach to the clevises 43 respectively and then diverging from eachother upwardly are attached at their other ends to the two eye bolts 47respectively carriedby the frame 38. The four cables 41 are attached tothecar 39, and at their other ends two to each of the eyes 44. Itis'seen that in one direction the car 39 is free to swing from thepoints of suspension at the eye bolts 47, and in the other direction, atright angles to the first named direction, the car is free to swing fromthe shaft 45 of the block 42. l

The starting motor and the'braking device for stopping the car areomitted from the drawing, but would be the same as shown in Figs 1 to 9inclusive. It is obvious also that the d evice could be operateddirectly by hand if desired.

A modified manner of securing the upper ends of the cables 40 is shownin Fig. 13; the cables 40, instead of attaching directly to eye bolts47, are secured to eyes 48 which pivot on the pins 49 each held. by twoeye bolts 50, shown as partly broken away. The suspending ropes, beingwidely spaced from one another, form means for preventing the car fromrotating on a vertical axis. The various forces acting on the car willbe insufficient to twist these ropes.

In operating the device, the passengers are permitted to come aboard thecar while it is resting at the position of equilibrium; the startingmotor is then operated to wind up its cable, the free end of said cablehaving previously been connected to the hereinbefore described catch forholding it, and as the cable is wound upon the drum of the startingmotor the car is drawn aside from its position of equilibrium in adirection diagonal to a line joining the points of suspension of the carfrom the frame, and when the extreme of the desired limit of movement ofthe car is neared, the said catch is tripped by the further movement ofthe car and automatically releases the end of the cable, and the car,now being released and not in a state of equilibrium, will start toswing by its own weight and will continue to freely swing as a result ofgravity and the acquired momentum due thereto, and, owing to thedirection in which it was drawn aside, the course followed by theswinging car will be the resultant of the two different periodicpendular motions, constituting what is known as a Lassajouss figure,which is described over and over again in gradually decreasing sizes,and, if left to itself, the car would eventually regain its originalposition of equilibrium; however,

the motion of the car is not allowed to die out,

as that would take too long, as well as its movements be too slighttoward the last, but when the desired number of swings have beenexecuted, or when the desired length of time has elapsed, the carisbrought to a stop by throwing the loop at the free end of the startingcable over the beforementioned catch for receiving it, the cable beingmostly wound upon its drum at the time and the car at one of itspositions of momentary rest, then the brake is applied to the drum uponwhich the cable is wound and the cable gradually paid out till the carreaches its position of equilibrium, when the passengers may disembarkand be replaced by others, and the performance be repeated ad infim'tum.When it is desired to change the form of the path over which theswinging car travels, the lock pin 27, holding the two intergearedadjusting rollers 17 and 21 from revolving, is removed and the saiddrums rotated in the one direction or the other as desired, thus, by themechanism previously described, causing the intermediate pulley block 6,whose shaft 8 is the fulcrum of the shorter component of the pendulum,to travel up or down, as already explained, thus lengthening orshortening the shorter of the two parts of the pendulum and changingtheir relative lengths to each other, as the longer component, whosefulcrum is the line joining the pulleys 11, 12, 13 and 14, remainsunchanged in length, and therefore, by causing a different ratio of thetwo peri' iodic motions, cause a different figure to be described by thecar'. In this way the ratios may be made anything desired, as 1 to 2, 2to 3, 3 to 4, etc., or anywhere intermediate.
